However, it should be understood that there is no intention to limit the various embodiments of the present application to the specific embodiments disclosed herein, but the present application should be understood to cover all adjustments, equivalents and / or alternatives within the spirit and scope of the various embodiments of the present application.

[0045] Hereinafter, the term "include" or "may include" used in various embodiments of the present application indicates the presence of a disclosed function, operation, or element, and does not limit the addition of one or more functions, operations, or elements. In addition, as used in various embodiments of the present application, the terms "include", "have", and their cognates are intended only to indicate a specific feature, number, step, operation, element, component, or combination of the foregoing, and should not be understood as first excluding the presence of one or more other features, numbers, steps, operations, elements, components, or a combination of the foregoing or the possibility of adding one or more features, numbers, steps, operations, elements, components, or a combination of the foregoing.

[0046] like Figure 1 , 6 , 7, and 10, a window cleaning machine, comprising:

[0047] Body 1;

[0048] A walking device 2 is arranged on a side of the machine body 1 facing the surface 5 to be cleaned, and is used to drive the window cleaning machine to operate;

[0049] The surface of the walking device 2 in contact with the surface to be cleaned 5 has a microstructure 3, and the microstructure 3 is used to at least partially embed with the microdefect 7 of the surface to be cleaned 5;

[0050] The microstructure 3 includes microprotrusions 31 and microchannels 32 formed between the microprotrusions 31 . The microprotrusions 31 and the microchannels 32 are used to be embedded with the microdefects 7 of the surface 5 to be cleaned, so as to increase the contact area between the walking device 2 and the surface 5 to be cleaned.

[0051] The walking device may be a roller, a crawler, a turntable, etc. The present invention is specifically described by taking a walking turntable as an example.

[0052] From a microscopic perspective, the surface to be cleaned 5, such as the glass surface, is not completely smooth, and there are many micro defects 7 on its surface. In addition, only a small part of the wiping surface of the existing window cleaning machine is in contact with the surface to be cleaned 5 (such as Fig.13 ), resulting in unsatisfactory contact between the window cleaning machine and the surface 5 to be cleaned, and the window cleaning machine may slip; based on this, the present application improves the structure of the walking device 2, and through the micro-protrusions 31 and micro-channels 32 on the walking device 2, enables the walking device 2 to better embed with the micro-defects 7 of the surface 5 to be cleaned, thereby increasing the contact area between the walking device 2 and the surface 5 to be cleaned, effectively avoiding the walking device 2 from slipping, the whole machine moving down or falling, and improving the safety and stability of the window cleaning machine; and the walking device 2 can effectively contact the surface 5 to be cleaned, which can further improve the cleaning effect of the window cleaning machine; and the window cleaning machine under this structure can adapt to cleaning surfaces of more sizes or shapes, and can more flexibly adapt to various cleaning scenarios.

[0053] Among them, Figure 3 , 5 As shown in Figures 9-12, the microstructure 3 includes a plurality of micro-protrusions 31 and a plurality of micro-channels 32. The plurality of micro-protrusions 31 are arranged in an array, and a micro-channel 32 is formed between two adjacent micro-protrusions 31. The micro-protrusions 31 include columnar micro-protrusions 31 or conical micro-protrusions 31, and the cross-sectional shape of the columnar micro-protrusions 31 or the cross-sectional shape of the conical micro-protrusions 31 includes a quadrilateral, a pentagon, a hexagon or a five-pointed star, etc.

[0054] In this embodiment, in order to ensure sufficient embedding of molecules at the microscopic level, the interaction force between molecules should be enhanced to increase the friction coefficient. Therefore, the surface roughness & dust particles (PM2.5) & experimental test data (operating driving force, wiping cleanliness, etc.) of the application scenarios of the window cleaning machine (such as the glass cleaning surface) are combined to obtain the structure of the micro-protrusion 31, and the micro-protrusion 31 is set to a columnar micro-protrusion 31 with a regular hexagonal cross-sectional shape, so that the microstructure and the surface material can bite each other to form a mechanical plowing force, effectively avoiding the walking device 2 from slipping, the whole machine moving down or falling, etc., thereby improving the safety and stability of the window cleaning machine.

[0055] Specifically, the shape of the columnar micro-protrusions 31 includes a regular hexagon with an inscribed circle diameter of 40-80 μm, the interval between two adjacent columnar micro-protrusions 31 is 4-8 μm, and the height of each columnar micro-protrusion 31 is 15-25 μm.

[0056] Preferably, the shape of the columnar micro-protrusions 31 comprises a regular hexagon with an inscribed circle diameter of 60 μm, the spacing between two adjacent columnar micro-protrusions 31 is 6 μm, and the height of each columnar micro-protrusion 31 is 20 μm. At this time, the columnar micro-protrusions 31 structure can be fully embedded between molecules at the microscopic level, greatly enhancing the interaction force between molecules to increase the friction coefficient, thereby achieving a good bite between the microstructure and the surface material to form a mechanical plowing force, effectively avoiding the walking device 2 from slipping, the whole machine moving down or falling, etc., thereby greatly improving the safety and stability of the window cleaning machine.

[0057] like Fig. 9 , 11 As shown, the microchannels 32 are connected to each other to form a microchannel network 33, and the microchannel network 33 is connected to the outside world. The microchannel network 33 is also used to accommodate various substances and to discharge various substances to the outside world. Among them, the various substances can be micro defects 7 on the surface 5 to be cleaned, dust particles on the surface 5 to be cleaned, sewage on the surface 5 to be cleaned, cleaning liquid and other substances. The present application forms a microchannel network 33 through microchannels 32 that are connected to each other, and the microchannel network 33 increases the accommodation space and flow space of the walking device 2, so that the microchannel network 33 can better accommodate various substances on the surface 5 to be cleaned, and the cleaning liquid on the microchannel network 33 is used to transport various substances to the outside world, thereby greatly improving the cleaning effect of the surface 5 to be cleaned.

[0058] Among them, the microfluidic network 33 is a plurality of microfluidic channels 32 staggeredly distributed from the inside of the walking device 2 to the outside of the walking device 2, and the adjacent microfluidic channels 32 are connected to form a well-connected structure. In this way, various substances contained in one microfluidic channel 32 can flow to other microfluidic channels 32. Among them, the microfluidic network 33 formed by each microfluidic channel 32 increases the area for accommodating various substances on the surface 5 to be cleaned, improves the dirt holding capacity, and the cleaning liquid can flow in the microfluidic network 33, thereby transporting various substances contained in the microfluidic network 33 to the outside, so as to further improve the cleaning effect of the surface 5 to be cleaned.

[0059] Among them, various substances include liquids, small particles or stains after cleaning.

[0060] like Figure 8 As shown, the surface of the walking device 2 in contact with the surface to be cleaned does not have the microstructure 3, or when the microstructure 3 just contacts the thin film 4 of the cleaning liquid, the thin film 4 of the cleaning liquid reduces the friction coefficient, thereby affecting the cleaning effect.

[0061] Based on this, in order to improve the cleanliness of the cleaning surface and increase the coordination of the cleaning liquid, the present application forms a stacked microstructure 345 between the microstructure 3, the thin film 4 of the cleaning liquid and the surface to be cleaned 5 through a special design between the microstructure 3, the thin film 4 of the cleaning liquid and the surface to be cleaned 5. Adjacent layer structures are inlaid with each other, so that the cleaning liquid can better adhere to the microstructure 3 and the cleaning liquid can better contact the surface to be cleaned 5, thereby making the structure more stable and improving its cleaning effect.

[0062] Specifically, when cleaning is performed using a cleaning liquid, a stacked microstructure 345 is formed between the microstructure 3, the thin film 4 of the cleaning liquid, and the surface to be cleaned 5, and adjacent layer structures are inlaid with each other. By setting the microstructure 3 to destroy the structure of the thin film 4 of the cleaning liquid, a stacked microstructure 345 is formed between the microstructure 3, the thin film 4 of the cleaning liquid, and the surface to be cleaned 5, and adjacent layer structures are inlaid with each other, so that the cleaning liquid can better adhere to the microstructure 3, and the cleaning liquid can better contact the surface to be cleaned 5, so that the structure is more stable and its cleaning effect is improved.

[0063] like Fig.14 As shown, the stacked microstructure 345 includes a first portion 3451 embedded in the micro defect 7 and a second portion 3452 embedded in the micro channel 32. The first portion 3451 is a cleaning liquid for deep cleaning the micro defect 7, and the second portion 3452 is a cleaning liquid for diversion. The cleaning liquid is pressed into the micro defect 7 of the surface 5 to be cleaned to form the first portion 3451.

[0064] The present application designs the stacked microstructure 345 at a microscopic level so that the micro defects 7 on the surface to be cleaned 5 can be deeply cleaned through the first part, thereby improving the cleaning effect of the surface to be cleaned 5, and the cleaning liquid guided by the second part can be allowed to flow fully, so that the cleaning liquid with dirt can be replaced in time after cleaning, thereby further improving the cleaning effect.

[0065] like Figure 1-8 As shown, when the cleaning liquid is sprayed on the surface to be cleaned 5 (such as glass), a thin film 4 of the cleaning liquid will be formed between the walking device 2 and the glass, so that the contact material of the friction coefficient is changed from the walking device 2 and the surface to be cleaned 5 to the walking device 2 and the thin film 4 of the cleaning liquid, thereby causing the friction coefficient to drop sharply, thereby causing the whole machine to slip, move down or fall.

[0066] Based on this, the present application forms a capillary channel (not shown in the figure) in the microchannel 32, and the capillary channel is used to absorb the cleaning liquid film 4 into the microchannel 32 and discharge it to the outside. The capillary channel can achieve sufficient infiltration of the cleaning liquid, and realize capillary adsorption of the walking device 2 and the cleaning liquid, so that the cleaning liquid film 4 is adsorbed into the microchannel 32 of the walking device 2, ensuring the stability of the friction coefficient, avoiding the whole machine from slipping, moving down or falling, etc., and greatly improving the stability of the window cleaning machine equipment.

[0067] The cleaning liquid film 4 includes cleaning liquid with dirt after cleaning.

[0068] like Fig.10 As shown, a traction effect is formed between the micro-channel 32 and the cleaning liquid, and the traction effect is used to draw the cleaning liquid into the micro-channel 32 .

[0069] When the cleaning fluid includes a cleaning liquid, a traction effect is formed between the micro-channel 32 and the cleaning liquid, and the traction effect is used to pull the cleaning liquid into the micro-channel 32 .

[0070] When the cleaning liquid includes multiple cleaning liquids, a traction effect is formed between the microchannel 32 and the cleaning liquids and between two adjacent cleaning liquids. The traction effect is used to pull the multiple cleaning liquids into the microchannel 32 .

[0071] The present application enables the cleaning liquid to enter the microchannel 32 through traction, thereby ensuring the stability of the friction coefficient, avoiding the whole machine from slipping, moving down or falling, and greatly improving the stability of the window cleaning machine equipment.

[0072] Among them, the pulling effect includes electrostatic attraction. Specifically, Fig.15As shown, when the whole machine is running, there will be dynamic movement of the cleaning liquid between the surface to be cleaned 5 and the walking device 2, so there will be interaction between the permanent dipole moments of the cleaning liquid molecules, one polar molecule of the cleaning liquid polarizes another molecule, generating an induced dipole moment and attracting each other, and the movement of electrons in the cleaning liquid molecules generates an instantaneous dipole moment, which instantaneously polarizes the adjacent molecules, which in turn enhances the instantaneous dipole moment of the original molecules; and this mutual coupling generates electrostatic attraction, which increases the macroscopic friction coefficient through electrostatic attraction, avoids the whole machine from slipping, moving down or falling, and greatly improves the stability of the window cleaning machine equipment.

[0073] like Figure 1-12 As shown, the walking device 2 rotates to discharge various substances in the microchannel network 33 to the outside.

[0074] Specifically, the walking device 2 is rotatably connected to the body 1, and a driving member is provided inside the body 1. The walking device 2 is configured to be driven to rotate by the driving member. When the walking device 2 rotates, a rotational centrifugal force is generated, thereby realizing the expulsion of various substances such as adsorbed liquid or dust, thereby expelling various substances from the outside and ensuring the dynamic balance of the total amount of liquid (such as cleaning liquid) inside the walking device 2.

[0075] like Figure 1 , 6 As shown in Figures 11, in the direction from the center of the walking device 2 to the outside world, the microchannel network 33 includes a plurality of branch channels 331. When the walking device 2 rotates, various substances are discharged from the plurality of branch channels 331 to the outside world. The present application greatly improves the discharge efficiency of various substances by providing a plurality of branch channels 331, reduces the risk of blockage by the diversion effect, ensures the smooth discharge of various substances, and thus speeds up the cleaning process. Secondly, the plurality of branch channels 331 significantly enhance the cleaning effect, so that the cleaning liquid can evenly cover the entire cleaning area, optimize fluid dynamics, and effectively remove various pollutants without leaving dead corners. In addition, the design of the plurality of branch channels 331 provides a variety of discharge paths with higher flexibility, enabling it to adapt to different scenarios and cleaning needs.

[0076] like Fig.10As shown, in the direction from the center of the walking device 2 to the outside world, the microchannel network 33 includes a plurality of connecting sections 332, each connecting section 332 at least connects to two connecting sections 332 in different directions downstream, so that the microchannel network 33 forms a plurality of branch channels 331. The present application is designed with a plurality of connecting sections 332, and each connecting section 332 at least connects to two connecting sections 332 in different directions downstream, so that various substances can be discharged from multiple directions, thereby improving the discharge efficiency, and the plurality of connecting ends form a plurality of branch channels 331 in the microchannel network 33, and the plurality of branch channels 331 greatly improves the discharge efficiency of various substances, reduces the risk of blockage through the diversion effect, ensures the smooth discharge of various substances, and thus speeds up the cleaning process. Secondly, the plurality of branch channels 331 significantly enhances the cleaning effect, so that the cleaning liquid can evenly cover the entire cleaning area, optimize fluid dynamics, effectively remove various pollutants, and leave no dead corners. In addition, the design of the plurality of branch channels 331 provides a variety of discharge paths, which has higher flexibility, so that it can adapt to different scenarios and cleaning needs.

[0077] like Figure 1 As shown, the window cleaning machine also includes a cleaning device 11, which is installed on the machine body 1. The cleaning device 11 is used to clean the surface to be cleaned. The present application provides the cleaning device 11 so that the cleaning device 11 contacts the surface to be cleaned, thereby removing various substances on the surface to be cleaned, so as to further improve the cleaning effect.

[0078] Among them, the cleaning device includes a cleaning cloth, a cleaning sponge, etc.

[0079] In one embodiment, the cleaning device and the walking device 2 are integrally formed, and the integrally formed design makes the structure more stable and compact.

[0080] In other embodiments, the cleaning device and the walking device 2 are detachable, and the detachable design facilitates the replacement of the cleaning device and improves the flexibility of use. The detachable setting can be achieved by Velcro, buckles, etc.

[0081] like Figure 1-4 As shown, in addition to designing the walking device 2 at the micro level, the present application also improves the walking device 2 at the macro level, specifically:

[0082] In the present application, a plurality of protrusions 8 are arranged on the walking device 2, and the plurality of protrusions 8 are arranged at intervals on the walking device 2, and a groove 9 is formed between each two adjacent protrusions 8, and each protrusion 8 has the aforementioned microstructure 3; when large particles 10 (pebbles, cement particles, etc.) are attached to the surface 5 to be cleaned, the walking device 2 passes through the surface 5 to be cleaned and accommodates the large particles 10 into the groove 9, so that the friction coefficient between the walking device 2 and the surface 5 to be cleaned remains unchanged, thereby preventing the whole machine from sliding down; further, the microstructure 3 on the protrusion 8 can be aligned with the surface 5 to be cleaned. The micro defects 7 of the surface 5 are inlaid, thereby increasing the contact area between the running device 2 and the surface 5 to be cleaned, further avoiding the phenomenon of the running device 2 slipping, the whole machine moving down or falling, etc., and improving the safety and stability of the window cleaning machine; and the microfluidic network 33 in the microstructure 3 increases the accommodation space and flow space of the running device 2, so that the microfluidic network 33 can better accommodate various substances on the surface 5 to be cleaned, and various substances are transported to the outside through the cleaning liquid on the microfluidic network 33, thereby greatly improving the cleaning effect of the surface 5 to be cleaned. Furthermore, the capillary channel (not shown in the figure) on the microstructure 3 can achieve full infiltration of the cleaning liquid, realize capillary adsorption of the running device 2 and the cleaning liquid, so that the thin film 4 of the cleaning liquid is adsorbed into the microfluidic channel 32 of the running device 2, ensuring the stability of the friction coefficient, avoiding the phenomenon of the whole machine slipping, moving down or falling, etc., and greatly improving the stability of the window cleaning machine equipment. The microchannel 32 and the cleaning liquid form a traction effect, which ensures the stability of the friction coefficient, avoids the whole machine from slipping, moving down or falling, and greatly improves the stability of the window cleaning machine. The window cleaning machine of the present application optimizes the structure of the walking device 2 at the macro and micro levels, integrates the capillary adsorption between substances, mechanical plowing force, van der Waals force, elastic deformation force and other functions, and realizes the constant driving force of the whole machine under different working conditions.
